Until HTC actually ships the update, this is meaningless. I can still recall their claims for updates (ala Thunderbolt and others) in the past-subject-to-revision when it becomes too hard/too long. I won't be fooled again. The One was released in March of 2013. If the dev preview is available in June, then 90 days after puts them very close to just past their 18-months of updates for the One (M7).Reply

Whatever the date was, I remember finally getting ICS on my Thunderbolt around the time of KitKat and right before I replaced the phone... talk about a late, pointless exercise. I don't know if HTC or Verizon or both was to blame, but what a way to treat your customers!Reply

They are not saying it will be available 90 days after the dev preview has been made available. They are saying an update will be available within 90 days after the final/stable release of Android L has been made available to them. That also makes a lot more sense (no pun intended) since the release date for Android L is "fall".Reply
